Vs claims. (c1. 1er- 133) This invention relates to an attachment'for a vtabulating" machine to adapt said machine tothe use of continuous-form stationery strips which 1 may be drawn around the powerdriven rotatable A further object of the invention is to provide l an improved attachmentwherein endless belt 1 conveyer members may be `readily moved to accommodate various lateral spacings -of perfora- Another object of the invention is to provide improved guide means for. conducting thexsta 1 The linvention is illustrated in a preferred em-.

Figure 1 is a side elevational viewof an attrunnion I5 which fit-into sockets on the tabulating machine and hold thedevice in proper position. -The lower cross rod II is provided with some laterally adjustable collars I6 which support stationery guide members II provided with lateral flanges I'Ia.` h y .The cradle members B, see Figures 3 and 4, are skeleton channel-like vmembersV whose sides I8 are providedwith upwardlyextending slots I9 and forwardly extending slots 20. The lower portions of` the arms I8 are cut away so as to slip readily over the square rods I0 `and are secured thereto by. .winged screws 2|; A number of cradle-membersmay be xed tothe bars -ID in suitable spaced relation and the conveyer memf bers C may be transferred from one cradle member to another to accommodate the spacing in s the particular stationery being used in the maa change -is made. l v y Oneor more ronveyer members may be emchine atany particular time. This makes it possible lto change from one stationery to another very quickly and it is unnecessary to carefully measure and adjustthe deviceeach time ployedandthese vdevices each comprise a housing22 equippedat its lower end withha sprocket tachment embodyingthe inventionshowing how the stationery passes through the bottomrof the tending xed trunnion I 4 and a spring'held wheel .23, having an'eight-point star socket 23a. to receive a square drive shaft`, .an d atits upper end `With an idler wheel 24 to keepl'lhe chain 25 attachment, around the platen roll and over the properly tensioned.

As shown in Figure 2 guide mem' the attachment is provided .with an inwardly exbers 3l are secured to the bars 29 for lateral attachment and serve to direct the perforations in machine. "mitted by the platen roll, the gear 44does not This'device comprises a continuously operatingVA motor 35 which makes a frictional driving connection with the drive shaft 26 and thereby with the platen roll. The motorv may be turned oi when the device is out of service by means of a toggle switch 36 and preferably a red signal light 31 is connected in series with the motor circuit so that the operator may be reminded that-the motor is running.

'I'he motor 35 through a suitable gear reduction 38 drives a shaft 39 which is disposed parallel tothe axis of the platen. A sleeveY 40 having a fiange 40a ,is vsecured to shaft 39 by means of a set screw 4Gb. A facing of frictional material 4I vis secured to the flange 40a. A flanged sleeve 4,2, also provided with a frictional face 43, is

splined to the sleeve 40 by means of a set screw 42a. A gear 44 having a bronze bushing 44a is journalledon the sleeve 40 and is frictionally engaged by the faces 4| and 43 by the compression spring 45 pressing against the member 42 and a ring 46 secured to the sleeve 40 by a set screw 46a. Thegear 44 is in mesh withv a gear 41 which is journalled on a shaft 48 and is adapted to vdrive the same, in one direction, through a roller-wedge type clutch 49, best shown in Figures 6 Aand 8. The other end of the shaft 48 is provided with a fixed gear 50 which is in mesh with gear 21 on the square drive shaft 26.

Ihus it will be understood that`when the motor 35 is running, it'tends to drive the shaft 26 in a direction to advance vthe stationery `and is restrained by the platen 21a `of the tabulating Except for the intermittent feed permove but is pressed for movement with the roguide plates I1, around the platen roll of the tabulating machine, and up over the conveyer members beneath the guide bars 29. The perforations are slipped over the feed pins a and the lines on the forms are adjusted with respect to the typing mechanism of the tabulating machine by movement of the star wheel detent knob 28d. The switch 36 may then be thrown on and the first form turned up into writing position by means of the knob 26a. The device is then ready to operate automatically in cooperation with the movement of the Platen of the machine. f

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom for some modifications will be obvious to those skilled in the art.

I claim:

1. In a duplicating machine having a power driven platen roll and paper feed means geared to said platen roll-for drawing continuous strips A of stationery through writing position, a power tating disks 4I and 43 of thefriction clutch;

The amount of driving force thus exerted on the gear 44 may be regulated by adjusting the pressure on the spring 45 by means of the ring 46.

`booster-for Vthe paper feed means, comprising:

an electric motor adapted to run continuously; and a frictional slip driving connection between said motor and platen roll adjusted Vto urge rotation constantly in the direction to advance v the stationery, .and means for controlling said rotation independently of the motor.

'2. A device as specified in claim l, in which the frictional slip driving connection includes a 'gear embraced byva pair of friction disks on a shaft driven by the motor.

3. vA device as specified in claim 1, in which the frictional slip driving connection includes a gear embraced by a pair of friction disks, one

of said disks being Afixed to a shaft driven by the motor and the other disk being splined to said vshaft and being urgedby a spring intocontact with said gear.

4. A device as specified in claim 1,'in whichthe frictionalslip driving connection includes a train of gears driven by a pair offriction disks provided on a shaft driven by the motor, and a roller clutch is provided in said train of gears so that the platen roll may be moved4 forwardly without moving the gear between the friction disks but which will drive the entire train when rotated rearwardly.

5. A continuous-form stationery attachment for a tabulating machine having a power driven platen roll, comprising: a frame provided with a drive shaft adapted to be geared to the platen, paper feed means having a lower drive wheel splined to said shaft, and a power booster for the paper feed means comprising a continuously operating motor having a frictional slip driving connection with the drive shaft.'
